Wiring clamp for mechanical characteristic test of circuit breaker

Technical Field

The utility model relates to a distribution appurtenance technical field especially relates to a experimental binding clip of circuit breaker mechanical properties.

Background

In recent years, under the guiding concept of constructing a strong power grid with an extra-high voltage power grid as a backbone grid frame and coordinately developing all levels of power grids, each power grid enters a high-speed development period, more and more transformer substations are governed by companies, more and more breaker devices belong to 110kV or above voltage levels, and in order to ensure the power supply reliability of the power grid, the routine maintenance working time is continuously compressed, and workers are required to guarantee quality and quantity and efficiently finish various works.

In the mechanical characteristic test process of the circuit breaker, wiring is required to be conducted on a switching-on terminal row in a circuit breaker control cubicle, and due to the fact that test wiring needs to be frequently replaced, the existing test wiring method is that 2 to 3 testers hold a test probe to be in contact with a switching-off and switching-on terminal, and the good contact can be achieved only by pressing forcefully. The test method is easily affected by human factors to cause poor contact between the probe and the terminal block, so that the condition of single-phase switching-off or single-phase switching-on occurs during the test of the circuit breaker, 220V direct-current pulse voltage can be applied to the probe when a tester holds the probe, and the direct-current voltage can be continuously output when an instrument fails, so that the personal safety is endangered.
